Zirconium refractory bricks are refractory bricks made of zirconia (ZrO2) and zircon (ZrSiO4), including zircon bricks, zircon mullite bricks and zircon corundum bricks.

Zirconium refractory bricks are different from silicon-aluminum refractory bricks and carbon-containing series refractory bricks. They have good slag resistance, low thermal expansion rate, thermal conductivity decreases with increasing temperature, high load softening temperature, and high wear resistance. It has good thermal shock resistance and has become an important material in various industrial fields. Zirconium refractory bricks have the characteristics of high melting point, low thermal conductivity, good chemical stability, etc., especially have good corrosion resistance to molten glass.

Application of zirconium refractory brick in glass kiln

Zirconium refractory bricks are mainly used in the large slag of glass melting furnaces, fire viewing holes, detection holes, breast walls of melting parts, arch feet, and sealing layers at the bottom of pools.
